    Save and publish

    Keep editable local projects and export SVG or 1×–4× PNG, JPEG and WebP artwork.

Frequently asked questions

Are screenshots uploaded?

No. Decode, SVG composition, raster rendering, project storage and download all run locally.

Can I hide sensitive data?

Yes. Add blur or solid redaction regions before export, but always inspect the downloaded result before sharing.

Why is export resolution limited?

A 64-megapixel output budget prevents large canvases and 4× export from exhausting browser memory.

Can it capture a webpage URL?

No. Arbitrary URL capture is restricted by cross-origin and authentication boundaries; paste or open a screenshot instead.
